摘要
研究更为广泛的同时具有交时滞,无穷时滞及反馈控制的n-种群竞争模型,并且以重合度理论和Lyapunov泛函为主要工具,得到了保证模型正周期解存在和全局吸引的充分性条件,所得结论推广了已有结果.
By using the method of coincidence degree and Liapunov functional, the existence and global attractivity of positive periodic solution of single species model with feedback regulation and infinite delay are studied some new criteria are established which in prove and generalize some know results.
